Test Details
Methodology
Liquid chromatography/tandem mass spectrometry (LC/MS-MS) after chromatography and solvent extraction
Result Turnaround Time
6 - 8 days
Turnaround time is defined as the usual number of days from the date of pickup of a specimen for testing to when the result is released to the ordering provider. In some cases, additional time should be allowed for additional confirmatory or additional reflex tests. Testing schedules may vary.
Special Instructions
Submit two tubes; one vial labeled as baseline and one labeled as post-metyrapone.

Serum (preferred) or plasma, frozen
Volume
0.5 mL (each specimen)
Minimum Volume
0.2 mL (each specimen) (Note: This volume does not allow for repeat testing.)
